Lark's list is very helpful. The books she does not recommend seem to plague the shelves of new-age sections in book shops, and I am sad to say I own a Silver Ravenwolf book, I refuse to get rid of it simply because it cost me a lot.
Out of the list lark gave you I have read all but two. One of my first books on wicca (when I was exploring that path) was the one by Thea Sabin, I can honestly say it was a concise, yet informative introduction to wicca written in a style which was easy to understand and comprehend. If you are just beginning to research your path I would start by purchasing this one. Of course this is just my opinion.
